Borosilicate Blocks for Chimney Liner Retrofit

[Inzynier]

I am looking for information on manufacturers of borosilicate blocks commonly used for chimney liners. The only product I am aware of is Pennguard block manufactured by Hadek. It is an excellent productr, but some of our customers ask for alternate sources. If you are aware of other producers, please reply.

I believe that Pennguard Block is manufactured by Pittsburgh Corning. Hadek are a marketing/design/installer of the Pennguard product. There are alternative manufacturers of both the Borosilicate Block and the Elastomeric Adhesive.

Ergon Armor now own Henkel (Corrosion Engineering). The Pennguard Block product is now part of the Ergon portfolio of materials. Ergon are manufacturing mortars, screeds and membranes. Pittsburgh Corning produce the Borosilicate glass block, labelled for Ergon as Pennguard Block. Equivalent materials are available which have been used in over 20 chimneys.

I am somewhat puzzled - which are the competing brands?

I know Ecocera and Blome. Blome are being run by an ex Henkel guy. Blome are a small version of Ergon, selling chemical resistant mortars, coatings and membranes. The GI-180 material is of a lower quality than Pennguard Block (lower density and less boron). What exactly are you wanting? Perhaps you should e-mail me with your requirements/plans for chimney linings: david@anticorrosion-eu.com I should be able to help.
